This article is based on a research I undertook in Belgium and Wisconsin in 2006-10. The purpose of this research was to identify the conditions required for healing based on myth to occur. Results show the importance of the role played by therapists in providing their patients with interpretation keys enabling them to employ a particular narrative as a mirror for their personal experience. As far as this condition is met, the fact that therapists and their clients do or do not belong to a same cultural system appears to have little importance. In other words, the transformative potential of a narrative would depend mainly on how it is presented to the subject and how it is believed.
